I am not sure if I am 100 % symptom free because after fighting this for almost two years, starting when I still had it in and sick, I don't know if I know that feeling. For me, the worst symptom that kept me from functioning normally was brain fog. It is not gone entirely but I can now work and go about my day normally. I still have nerve pain here and there but it passes faster than it used to. I feel weak and dizzy sometimes too, I just press forward and it seems to go away. PMS is horrible but the worst of it is only a couple of days. I only have the extreme tiredness during PMS...I am tired most of the time but I work and have a family.
I have noticed that I think about it less and less which makes me know that I am getting better. At one point, I could hardly drive or go to the grocery store but it is much better now.
Hope you get some relief soon, I know that it has been a long road for you !!
